16 3. WIRING! WARNING To prevent electric shock or instrument failure, do not turn on the power until all wiring is completed. Make sure that the wiring is correct before applying power to the instrument. To prevent injury to persons, damage to instrument and equipment, a suitable external protection device shall be required. To prevent instrument damage as a result of failure, protect the power line and the input/output lines from high currents with a suitable overcurrent protection device with adequate breaking capacity such as a fuse, circuit breaker, etc. 3.1 Cautions for wiring (1) For thermocouple input, use the appropriate compensation wire. (2) For RTD input, use low resistance lead wire with no difference in resistance between the three lead wires. (3) To avoid noise induction, keep input signal wire away from instrument power line, load lines and power lines of other electric equipment. (4) Signal connected to Voltage input and Current input shall be low voltage defined as SELV circuit per IEC (5) When a shielded lead is used, ground the shield as follows to prevent noise generated by both stray capacitance between the shield and each conductor, and by the shield potential difference with the earth. 16

17 When signal source is grounded, ground the shield to the signal source side. Signal source Instrument Shield When signal source is not grounded, ground the shield to the instrument side. Signal source Instrument Shield (6) If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter. Shorten the distance between the twisted power supply wire pitches to achieve the most effective noise reduction. Always install the noise filter on a grounded panel. Minimize the wiring distance between the noise filter output and the instrument power supply terminals to achieve the most effective noise reduction. Do not connect fuses or switches to the noise filter output wiring as this will reduce the effectiveness of the noise filter. Instrument power Twist these leadwires IN Shorten distance between pitches 17 Noise filter Twist these leadwires OUT Minimize distance Instrument power terminals

18 (7) For wiring, use electric wires conforming to the domestic standard of each country. For power supply wires, use 600 V Polyvinyl chloride insulated wires (JIS C3307). Ground the instrument to the earth through the shortest route possible using an electric wire with a nominal conductor cross section of 2.0 mm 2 or larger. [Grounding resistance: Less than 100 ] (8) Allow approximately 3 seconds for contact output when the instrument is turned on. Use a delay relay when the output line, is used for an external interlock circuit. (9) Power supply wiring must be twisted and have a low voltage drop. (10) This instrument with 24 V power supply is not provided with an overcurrent protection device. For safety install an overcurrent protection device (such as fuse) with adequate breaking capacity close to the instrument. Fuse type: Time-lag fuse (Approved fuse according IEC and/or UL248-14) Fuse rating: Rated current: 0.63 A (11) For an instrument with 24 V power supply input, supply power from "SELV" circuit defined as IEC (12) A suitable power supply should be considered in end-use equipment. The power supply must be in compliance with a limited-energy circuits (maximum available current of 8 A). (13) Display accuracy of current transformer (CT) input value at heater break alarm is within 5 % of input value or 2 A, whichever is greater. Therefore, when a heater break alarm is used, set load current flowing through the current transformer (CT) at a value to be sufficiently large. (14) Use the solderless terminal appropriate to the screw size. Screw size: M3 x 8 Recommended tightening torque: 0.4 N m [4 kgf cm] Specified solderless terminals: With isolation Applicable wire: Solid/twisted wire of 2 mm 2 or less (15) Make sure that during field wiring parts of conductors cannot come into contact with adjacent conductive parts. 18
